Cannot install Docker on some machines: "WARNING: Cannot verify the file SHA256. Deleting the file."

Troubleshooting


Problem

IBM Planning Analytics Workspace (PAW) relies on Docker, which is a non-IBM software.
Docker can be installed on Windows Server 2016 by simply running these two commands in Powershell :
Install-Module DockerMsftProvider -Force
Install-Package Docker -ProviderName DockerMsftProvider -Force

But sometimes, on some machines, the Install-Package command may terminate with this error :
WARNING: Cannot verify the file SHA256. Deleting the file.

Sometimes it can be worked around by installing a specific version of Docker:
-Install the latest known build of 18.09.x version :
Install-Package -Name docker -ProviderName DockerMsftProvider -RequiredVersion 18.09 -Update -Force
-Install the latest known build of 18.03.x version :
Install-Package -Name docker -ProviderName DockerMsftProvider -RequiredVersion 18.03 -Update -Force
-Install the latest known build of 17.06.x version :
Install-Package -Name docker -ProviderName DockerMsftProvider -RequiredVersion 17.06 -Update -Force

But sometimes none of these commands work.
